Summary
The substr() method is deprecated in JavaScript and may cause issues or warnings in future versions. To ensure better compatibility and prevent potential runtime issues, we should replace all occurrences of substr() with slice().
Details
Currently, the following functions in index.js file contain instances of substr():
- JSONCookie(str) {}
- signedCookie (str, secret) {}
These should be refactored to use slice() instead.
Why It Should Be Fixed
JavaScript's substr() method has been deprecated. Refactoring to use slice() will future-proof the code and prevent potential issues in modern JavaScript environments. This change is necessary for compatibility with new ECMAScript standards and best practices.
Suggested Solution
Replace substr() with slice() in all occurrences.
